SAFETY-RAZOR.

SPECIFICATION forming part of Letters Patent No. 784,336, dated March '7, 1905.

Application filed August 5, 1904. Serial No. 219,604.

zors; and I do hereby declare that the follow.

ing is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in razor-guards adapted to be applied to form so-called safetyrazors; and it consists in certain features of novelty in the detail construction and arrangement of the clamping means therefor, all as hereinafter more fully described, and specifically pointed out in the claims.

The object of the invention is to provide a razor-guard which may be adapted for application to any ordinary razor without special fittings and adjustments of the parts thereof, whereby the guard may be quickly applied and as quickly removed from an ordinary razor-blade to form a safety-razor.

Referring to the drawings, in which similar numerals of reference indicate corresponding parts in all the views, Figure 1 is a side elevational view, partly broken away, shoving the razor equipped with my invention. Fig. 2 is a sectional view of Fig. 1 looking in the direction indicated by the arrow; and Fig. 3 is a view approximately on the same line, showing one of the clamping-tongues in closed and one in open position.

Referring to the parts, 4 is a razor-blade, which is connected with the guard-plate 5 at its ends by means of the clamp 6 of common construction, the said guard 5 terminating at its lower edge portion in the teeth 7, which have integral lateral extensions 8 formed thereupon, as shown in Figs. 2 and 3.

The upper portion of the guard-plate 5 ter-,

hold the tongues 13 in the position shown in Fig. 1-that is, against the upper edge of the razor-blade 4.

When it is desired to place the razor-blade in position, all that is necessary is to throw the tongues 13 to the position indicated by the tongue 13*of Fig. 3, whereupon the blade may be set between the clamps 6 at each end of the guard-plate 5 and the tongues 13 thrown to the position shown in Fig. 1, wherein the pressure of the spring 10 against the cam extensions 15 of said tongues will cause a sufficient pressure to be exerted upon the upper edge portion of the razor-blade to hold it locked firmly in position, from which position it can only be removed upon raising the tongues 13.

In use the razor may be manipulated in the ordinary manner common to razors of this class.

WVhile I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. A razor-guard comprising a guard-plate, blade-clamps thereon, a laterally-projecting ledge on said guard-plate, a spring extending longitudinally thereof, and a locking-tongue pivotally mounted between said spring and said ledge.

2. A razor-guard comprising a guard-plate, blade-clamps thereon, a laterally-projecting ledge on said guard-plate, a spring extending longitudinally thereof, and a cam-shaped locking-tongue pivotallymounted between said spring and said ledge.

3. A razor-guard comprising a guard-plate, 5 blade-clamps thereon, a laterally-projecting ledge on said guard-plate, a spring extending longitudinally thereof, and a plurality of tongues each of which has integral pintles and cam extensions, said tongues being mounted between said spring and said ledge. To

In witness whereof I have hereunto set my hand in the presence of two witnesses.
